ALEXANDER STEWART, OF PHILADELPHIA, PENNSYLVANIA.

CUSPIDOR.

SPECIFICATION forming' part of Letters Patent No. 276,496, dated April24, 1883. Application filed November 13, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER STEWART, a citizen of' the United States,residing at Philadelphia, in the county of Philadelphia `and State ofPennsylvania, have invented cer cuspidon Fig. 2 is a transverse sectionof breast, or of bottom shell.

My invention has for its object to provide a sheet-metal-cuspidor, whichshall be stronger and more durable than any heretofore produced, andwhich will require but very little, if any, more material than thatneeded for cuspidors made in the ordinary manner.

My improvements consist, rst, in making a sheet-metal cuspidorcorrugated; and, second, in the special construction of a corrugatedsheet-metal cuspidor, as hereinafter fully 'set forth.

V l Referring to the accompanying drawings, A represents a sheetmetalcuspidor comprising a throat, B, breast- C, bottom shell, D, and footE.The bottom shell is composed of the `bottom d and the wall or side d.The throat and breast are made in separate pieces joined atjHb. Thebottom shell, D, is also a separate piece, and is joined to the breastat c.n The Toot E may be usedor not, as desired, being `constructed and,if used, attached in the usual 0r any suitable manner. The throat,breast, and bottom shell are corrugated, substantially as shown in thedrawings, theicorrugations being vertical,` and preferably produced inthe act of forming the said parts by stampin g or pressing flat platesof sheetmetal, as described in Letters Patent of the United Statesgranted to me, dated October 24,1882,`N"o. 266,548. The footE may bealso corrugated, similarly to the throat, breast, and bottom shell. Bypreference the corrugations do not extend to the edges of the specifiedparts of the cuspidor,

l said edges, or the metal adjacent thereto, being left plain, so as toproduce smooth or plain joints where-the parts meet at b c, and topermit the formation of a like plain or smooth wire edge or rim, b', forthe throat. In some cases, however, I may corrugate the edges, or 'havethe corrugations extend to the edges and make the joints and wired edgeon the corrugations. The corrugation ofthe metal imparts great strengthto the vessel, so that the material used in the manufacture of the samemay be quite thin. The amount of metal thus required is very little, ifany, more than that needed for cuspidors of the ordinary construction,while the corrugated cuspidors are vastly stronger and more durablethanpthers.

In practical use ordinary sheet-metal cuspidors tend-to break down orcave in in the throat and breast, owing to their being pressed intoservice as foot rests or supports; and they are also liable to have thebottom shell dented/in the side by cont-act with the feet of personsmeeting or moving them. By making these parts corrugated, greatlyincreased powers of resistance are imparted to the vessels, renderingthem stronger and more durable, without materially increasing their costof production or weight.

AWhat I claim asmyinvention is as follows vember, 1882. I
